Traditional teacher education programs focus on pedagogy and, to a lesser extent, assessments of knowledge (Siedlecki, 2012). Pedagogy and assessments should be fundamental components of any secondary teacher's curriculum planning (Knight, Shum, & Littleton, 2014). This study sought to consider the possible effects of three pedagogical…

Effective software testing identifies potential bugs and helps correct them, producing more reliable and maintainable software. As software development processes have evolved, incremental testing techniques have grown in popularity, particularly with introduction of test-driven development (TDD). However, many programmers struggle to adopt TDD's…

Subscores, also known as domain scores, diagnostic scores, or trait scores, can help determine test-takers' relative strengths and weaknesses and appropriately focus remediation. However, subscores often have poor psychometric properties, particularly reliability and distinctiveness (Folske, Gessaroli, & Swanson, 1999; Monaghan, 2006;…

Many methods exist for imputing missing data but fewer methods have been proposed to test the missing data mechanism. Little (1988) introduced a multivariate chi-square test for the missing completely at random data mechanism (MCAR) that compares observed means for each pattern with expectation-maximization (EM) estimated means. As an alternative,…

The purpose of this study was to examine influences of standards-based reform and high-stakes testing on teacher practices and perceptions in high school science classrooms. A literature review suggested that teacher practices and perceptions are affected by emphasis on standards-based reform and high-stakes testing and that state level…
